Integrated circuit with low energy consumption in a power saving mode

摘要

The invention proposes an integrated circuit with at least one voltage regulator connected between a supply potential connection and a reference potential connection, which furthermore has at least one useful circuit containing memory and / or logic, the supply potential input of which is coupled to an output of the voltage regulator. According to the invention, the voltage regulator can be switched off via a first switching device in a power saving mode. The supply potential input of the useful circuit is then connected to the supply potential connection via a diode circuit.
